Nui is a great host! He's very communicative and helpful. This was my first trip to Bangkok and he gave me enough information to go wander, knowing what I'm doing. He also helped me with couple of requests I had for him regarding other reservations.
Place is very secure, clean, close to BTS, plenty of local food around, great for family or individual and feels like home.
I absolutely recommend Nui for your next host, if you're traveling to Bangkok.
